To all vwhom it may concern-.- I j Be it known that ALLEN $0011, acitizen of the United States, residin at Omaha,

in the county of Douglas and tate of Neful Improvements in ShippingContainers, of which the following is a specificat on.

The present invention relates to shlpplng containers and particularly tothat type 10 adapted for thermatically sealing ice cream and thelike'for shipment. 1

An object of he present invention ls to provide a container of thischaracter which will seal and protect the contents of thecon- 1 taineragainst temperature changes, so that frozen material or articles may besafely shipped, and will, remain intact for long eriods of time, such asfor upwards of iburteen hours. 7 I a Another object'of the invention isto provide a container which is constructed par ticularly for use [inshipping uantities of ice cream without the use of me and salt water, sothat the contents of the container 2 is not liable to injury incident tothe seepage of salt waterinto the inner can or compartment, and whichwill automatically condition the ice cream, so that it may be scoopedout or removed from the container after it reaches its destination. Inconnection with this object it is well known that under presentconditions after a can of 1ce cream is shipped and reaches its destnation it frequently is frozen so hard that it cannot be scooped out. ofthe container until it has been exposed for some time, so as to softenthe bulk of the ice cream at the top, the cream softening as it is beingdished out. Another object of the invention is to provide a heatinsulating container with a flexible cover and a flexible hinge, so thatthe cover may be tight] bound in place over the container to hold t ecan or receptacle rig- 4 idl in position during shipment and which wi linsure the exclusion of air from the top of the container. I c v Anotherobject of the invention is to provide an im roved cover which may notonly be adjusted so as to be tightly bound about 'the upper end of thecontainer, but which may be sealed in place so as to preventunauthorized access to the interior of the container without detection.

With the foregoing and other objects in Figure dis a similar view of theo outer? walls, and the chambers view, the invention will be more fullydescribed hereinafter, and will be more par- 1 ticularly pointed'out inthe claims appended hereto. I 5 braska, has ,invented certain new anduse In the drawings, wherein like symbols to refer to like orcorresponding parts throughout the several'views, Y I I Figure 1 is anelevation of a shipping container constructed according to the pres entinvention, parts of the same being broken away and shown in section, andan ice cream receptacle being shown in position therein.

-Referring to the drawings the container comprises a body portion madeup of concentrically spaced walls. Theinner wall is composed of a smoothla er of fibe rvlt) surrounded by a closely -tting layer '11 ofcorrugated fiber board providing dead air cells about the layer 10. Theouter wall of the container is made up of adjacent smooth layers 12 and13 of fiberboard or the like preferably covered on the exterior with alayer of canvas 14 of suitable strength and forming the exterior coverof the contai'ner. The inner and outer walls of the container are spacedapart by, three pairs 95 of fiber rings 15, 16 and 17 arrangedrespectively at the top, the intermediate and the bottom portions of thecontainer for reinforcing and stren thening the same and maintaining thewalls in suitably spaced relation throughout the entire height of the Icontainer.

The intermediate rings 16 are providedwith relatively large openings 18there-1 through which intercommunicate the upper and lower chambersbetween the inner and are preferabl filled with a body of powdered cork19 w ich is'ciosely packed in the chambers to prevent tree circulationoff air and to on Ia pair of insulate the walls one from the other. Thepowdered cork is adapted to settle through the openings 18 from onechamber to the other as the container is handled so that the denserportion of the cork filler 19 is at the bottom and intermediate parts ofthe container, and so that the lighter packed;

portion of the filler is at the top of the container where it is notdesired to maintain such an effective seal, and so that the ingredientsin the top of the container may melt more rapidly than the remainder ofthe bulk. The openings 18 prevent the formation of a loosely packed massof the cork at the intermediate portion of the container which wouldotherwise destroy the continuous solid insulation and would re sult inthe softening of the frozen material at an intermediate point instead ofat the top. The inner wall provides a compartment or storage space andthe. latter is provided with a false bottom 20 comprising a pair offiber discs superposed upon each other and supported by strips or blocks21 of fiber which are in built u formation to the desired height andwhic are of small surface area to provide chambers orspaces .thereaboutand at opposite sides for'a botlayer 25 of heavy canvas or the like,which not'only extends beneaththe container, but also up the exterior'sides thereof .for a suitable distance as shown. A bufiing ring 26ofrope or the like is secured about the lower edge portion of thecontainer to prevent dama e to the same in rough handling,

. rolling an the like.

The inner compartment is provided with a lining 27 of canvas which iswaxed or dipped in parafiin, the layer 27'extend1ng across the falsebottom 20 and also up the inner sides of the inner wall of thecontainer. This forms the interior compartment which is adapted toreceive a receptacle or can 28adapted to contain ice cream or the likeand which is provided with a removable cover 29 on its upper end in theusual manner. I

The container is provided with a cover 30 which is in the form; of adisc or cap adapted to seat over the entire top of the container andwhich is made u of an outer layer of canvas and an innerayer of canvas31 between which'are imposed layers of flax or wool 32 forming a heatnon-conduct ing pad, the resiliency of the layers 32 is thus held inrigid position by reason 0 block -21 is supported upforming a cushionadapted to force the innerlayer of canvas 31 down into the compartmentof the container and against the top 29 of the receptacle. Thereceptacle this pad or packing at its top. .The cap or closure 30 asformed, is provided with a flexibleflange or skirt 33 which is stretchedalong the outer edge of he canvas layer, and which is adapted to extenddown to an appreciable extent over the top ofthe container. The skirt 33is interrupted atone side to provide an ample space for permitting theskirt to be contracted about the 'container and to accomplish thisresult the skirt 33 is provided at one side and near its lower edge witha strap 34 adapted to engage adjustably and detachabljr. with a buckle35 secured to the opposite lower edge portion of the skirt. The strap34-is adapted to be drawn taut through the buckle in order to contractthe skirt tightly about the upper edge of the container.

At this interrupted portion of the skirt 33 is located a flexible hingestri 36 formed of leather or the like stretche' at its upper end to thecap or closure 30 andwhichis preferably of greater width than the spacebetween the separated edges of the s irt toextend therebetween andpermit of the uninterrupted adEstment of the skirt. The binding of the s'rt over the opposite edge portionsof the hinge strip 36 also hold thelatter flat against the container and bind the hinged str1p against 'thecontainer to form the interrupted portion of the skirt and thusefl'ectively close and seal the cap upon the container. The lower edgeportion of the strip 36 is stretched or otherwise suit? ably secured tothe container along a 'line adjacent to the lower edge of the skirt sothat the hinge strip in appearance forms substantially a continuation ofthe skirt.

The container may be rovided with a flexible hand stra 37 which ispreferably secured at one on beneath the hinge strap 36 to the outerside of the container and at its other end is preferably secured to theopposite side of the container, so that the the cover when it isdesiredto open the same.

' In order to prevent unauthorized tam ering with the contents of thecontainer uring shipment, and without detection, the skirt 33 isprovided at one side, preferably opposite-to the hinged strap 36, withan eye piece 38 secured through the skirt and which is adapted toregister with a ring or loop 39 secured to theadjacent' side of thegontainer, the eye piece 38 and the ring 39 en: 40 t erethrough, theends of which are arranged to receive a sealing wire.

adapted to besecured beneath a suitably stamped seal 41 which may bearthe particular marks of the shipper.

I do not Wish to be restricted to the size, form, and proportions of thevarious parts, and obviously changes could be made in the constructionherein described Without departing from the spirit of the invention, itbeing only necessary that such changes fall within the scope of theappended claims.

What is claimed is v 1. A shipping container comprising a body portion,a cap fitting over the top of the body portion and including a heatnonconducting cushion adapted to be compressed against and into theupper end of the container, a flexible hinge strip connected at oppositeends to the container and to the cap, a flexible skirt depending fromthe cap about the container and overlapping said hinge strip, and meansfor drawing the 1 adapted to fit into the top of the container andprovided with a depending skirt adapted to encircle the upper end of thecontainer, an elongated hinge strap connecting the container to the cap,adjustable binding means carried by the skirt for drawing the same tautabout the container and over said hinge strap, an eye piece securedthrough a portion of the skirt, a ring secured to the container adjacentto the eye piece, and a sealing wire adapted to be se+ cured throughsaid e e piece and said ring.
